SPECIFICATION forming part of Letters Patent No. 349,638, datedSeptember 21. 1886.

Application tiled January 5, 1386. Renewed August 2E, 1886. Serial No.212,097. (No model.)

To all whom it may concern.-

Be it known that we, ANDREW J. FLoWERs and MALON I. FLOWERS, citizensofthe United States, residing at Springfield, in the county of Greeneand State of Missouri, have invented certain new and usei'ulIinproif'ements in Motors, of which the following` is a specification,reference being had therein to the accompanying, drawings.

Our invention relates to rotary engines, and our object is while runningan eccentric cylinder in a cylindrical case to form guides for thepistons which work in the eccentric cylinder, in order to give them amore steady and uniform movement, as will be hereinafter more fully setforth.

In the accon'ipanying drawings, making .part of this specification,Figure l represents avertieal section taken crosswise of thedrivingshaft. Fig. 2 is also a vertical section, but taken in line withthe shaft. Fig. 8 represents a plan view ot' the guide-ring and bottomView of the pistons.

In the figures, A represents the case of the machine', having acylindrical internal bore.

B B represent the heads of this case, which are bolted in place in anysuitable manner. C and D represent the inlet and outlet pipes of thiscase. In the head B is a circular recess,which is concentric with thebore ofthe case. In this recess is placed an annular ring, G, the outerface of which is Hush with the internal sui-tace ofthe head B.

E represents a skeleton cylinder having a driving-shaft, F, passingthrough it. The diameter ofthe cylinder E is less than that of the boreof the ease, thereby permitting said cylinder' to be placedeecentrically within said case. The shaft F has bearings in both ot' theheads. The cylinder E is so located in the ease that its periphery willtouch the internal surface of the case at a point between the inlet andoutlet pipes, as represented in Fig. l. Gut

from near the center of the cylinder E to its periphery are rect-angulargrooves or openings in which are placed the pistons II H. The

louter edges ot' these pistons are rounded, the

pistons being solid metal. The ring G is provided with two curved slots,c a. A pin or pins, tf1', pass through the slots c c and into one endofthe pistons. \Vhcn. the motor is in operation the ringGrcvolves, andthe pins t' i, playing in the slots c a, cause the pistons to moveoutward; 'lhe pistons are caused to move inward by the contact oftheinterior sur- L face ot' the case with the outer edges ot' said pistons.The pistons start to move outward when the periphery ot' the cylinderbegins to have contact with the internal su rl'ace ot' the case. Steamis thus taken in at one port, and, pressing upon the piston, causes thecylinder to revolve, the steam escaping at the next or exit port, thepiston after it passes it beingforced entirely within its recess, andthus the pistons are alternately moved outward and inward,so long assteam is admitted. rIhis motor may be used for steam or gas or water, asmay be desired, or may be used as a pump, submerged or suction.

Having thus fully described our invention, what we claim as new, anddesire to secure by Let-ters Patent, isy rlhe combination ot' the caseA, with iis inlet and outlet ports, the eccentrically placed cylindertherein, the pistons H H oli' said cylA inder, andV therslotteldconcentric. ring G. embedded in the head of the case, substantially asand for the purpose specified.

In testimony whereof` we affix our signatu re's in presence of twowitnesses.
